Preventing Marble Countertop Etching
Have you ever heard of s-b-s sealer or lifeguard from Aldon chemical?
The products are supposed to prevent etching on marble.
I would like to know if you have had experience with these products or similar and if they work well.
I put a marble tile countertop in and am only now, after the install, finding out about etching. How do you prevent marble etching?
ANSWER: The only 100% successful method
to prevent etching is to prevent contact of acidic or caustic liquids and cleaners with the marble surface.Chemical coatings can help but
do not absolutely prevent etching and do require upkeep and maintenance.
Coatings can be the answer in very high-use locations like hotels and bars, but generally, not the best idea for home as they can be more trouble than the problem they try to solve.
Aldon's sealer combo is a penetrating sealer that also leaves a layer on the surface and not completely below the surface like most/all other penetrating sealers.
Clearstone is another similar coating that helps prevent etching. Coatings that try to prevent etching can...
If your marble is polished
- Change the look of your stone possibly making it look plasitc.
- Require new or additional special maintenance (compared to an untreated marble countertop).
- Show wear (scuffs, scratches) more readily than the stone itself.
- Can be difficult to apply correctly or require expensive professional application.
- May be detrimental to the long-term integrity of the stone.
then note that you may have some difficulty getting the SBS and Lifeguard to absorb and bond properly. Though Aldon claims their spray on SBS is designed for low porosity surfaces like polished marble.
Aldon appears to claim that their sealer / coatings won't scuff easily and that it
doesn't need stripping to touch up or reapply (when damaged by etching or scratches, etc.)
If that is true, then it could be a very good product to use for certain finishes, but I don't know that I'd recommend it for all finishes, especially honed or tumbled unless you want that "wet look."
Plus honed marble doesn't show etching that badly anyway.One more thing
is that SBS contains methylene chloride which is a powerful, noxious and toxic solvent. I highly recommend using a respirator if you do use this product and also expect your house to be filled with fumes for 2-3 days.
And I wouldn't put marble sealed with Aldon in the same category as granite for use in the kitchen. Even if
marble etching can be controlled, granite is still much more durable and a better choice for kitchen countertops.
These types of coatings can be beneficial in certain limited situations like commercial installations where a marble cleaning and maintenance team is constantly caring for the surface.
If you do decide to apply a topical coating, definitely test your complete application procedure on a left-over tile first to see what the sealer will do... how it will look. To prevent etching I recommend
you simply follow the marble care Do's & Don'ts
to learn how to properly care for and clean marble and you will effectively prevent 90% of etch marks.
No need to complicate matters by applying a permanent topical coating especially when most etch marks on polished marble, travertine or limestone can be easily restored using the ETCH REMOVER / Marble Polishing Paste
If you do use a coating, please report back about how it goes, how you like the end result and if it works!
